Salton City is a census-designated place (CDP) in Imperial County, California. It is the largest Imperial County development on the Salton Sea coast. It is part of the El Centro, California Metropolitan Statistical Area. The population was 3,763 at the 2010 census, up from 978 in 2000. The reported population for 2020 was 5,155.
The Colorado River is one of the principal rivers in the Southwestern United States and northern Mexico. The 1,450-mile-long (2,330 km) river drains an expansive, arid watershed that encompasses parts of seven U.S. states and two Mexican states. The name Colorado derives from the Spanish language for "colored reddish" due to its heavy silt load. Starting in the central Rocky Mountains of Colorado, it flows generally southwest across the Colorado Plateau and through the Grand Canyon before reaching Lake Mead on the Arizona–Nevada border, where it turns south toward the international border. After entering Mexico, the Colorado approaches the mostly dry Colorado River Delta at the tip of the Gulf of California between Baja California and Sonora.
The Salton Sea is a shallow, landlocked, highly saline body of water in Riverside and Imperial counties at the southern end of the U.S. state of California. It lies on the San Andreas Fault within the Salton Trough that stretches to the Gulf of California in Mexico. Over millions of years, the Colorado River has flowed into the Imperial Valley and deposited alluvium (soil), creating fertile farmland, building up the terrain, and constantly moving its main course and river delta. For thousands of years, the river has alternately flowed into the valley, or diverted around it, creating either a saline lake called Lake Cahuilla, or a dry desert basin, respectively. When the Colorado River flows into the valley, the lake level depends on river flows and the balance between inflow and evaporative loss. When the river diverts around the valley, the lake dries completely, as it did around 1580. Hundreds of archaeological sites have been found in this region, indicating possibly long-term Native American villages and temporary camps.
The Imperial Valley of Southern California lies in Imperial and Riverside counties, with an urban area centered on the city of El Centro. The Valley is bordered by the Colorado River to the east and, in part, the Salton Sea to the west. Farther west lies the San Diego and Imperial County border. To the north is the Coachella Valley region of Riverside County, which together with Imperial Valley form the Salton Trough, or the Cahuilla Basin, also the county line of Imperial and Riverside counties, and to the south the international boundary with Mexico.
California's Colorado Desert is a part of the larger Sonoran Desert. It encompasses approximately 7 million acres, including the heavily irrigated Coachella and Imperial valleys. It is home to many unique flora and fauna.
The Imperial Diversion Dam is a concrete slab and buttress, ogee weir structure across the California/Arizona border, 18 miles (29 km) northeast of Yuma. Completed in 1938, the dam retains the waters of the Colorado River into the Imperial Reservoir before desilting and diversion into the All-American Canal, the Gila River, and the Yuma Project aqueduct. Between 1932 and 1940, the Imperial Irrigation District (IID) relied on the Inter-California Canal and the Imperial Canal and Alamo River.
The All-American Canal is an 82-mile (132 km) long aqueduct, located in southeastern California. It conveys water from the Colorado River into the Imperial Valley and to nine cities. It is the Imperial Valley's only water source, and replaced the Alamo Canal, which was located mostly in Mexico. The Imperial Dam, about 30 miles (48 km) northeast of Yuma, Arizona on the Colorado River, diverts water into the All-American Canal, which runs to just west of Calexico, California before its last branch heads mostly north into the Imperial Valley. Five smaller canals branching off the All-American Canal move water into the Imperial Valley. These canal systems irrigate up to 630,000 acres (250,000 ha) of crop land and have made possible a greatly increased crop yield in this area, originally one of the driest on earth. It is the largest irrigation canal in the world, carrying a maximum of 26,155 cubic feet per second (740.6 m3/s). Agricultural runoff from the All-American Canal drains into the Salton Sea.
The Salton Sink is the low point of an endorheic basin, a closed drainage system with no outflows to other bodies of water, in the Colorado Desert sub-region of the Sonoran Desert. The sink falls within the larger Salton Trough and separates the Coachella Valley from the Imperial Valley, which are also segments of the Salton Trough. The lowest point of the sink is 269 ft (82 m) below sea level, and since 1906 the 343 square miles (890 km2) Salton Sea has filled the lowest portion of the sink to a water depth of up to 43 ft (13 m).
The Alamo River flows west and north from the Mexicali Valley across the Imperial Valley (California). The 52-mile-long (84 km) river drains into the Salton Sea.
The New River flows north from near Cerro Prieto, through the city of Mexicali, Baja California, Mexico, into the United States through the city of Calexico, California, towards the Salton Sea. The river channel has existed since pre-historic times. The river as known today formed from a levee failure and massive flooding that filled the Salton Sea.
The Imperial Irrigation District (IID) is an irrigation district that serves the Imperial Valley in Southern California. Established under the State Water Code, the IID supplies roughly 500,000 acres (200,000 ha) of Imperial Valley farmland with raw Colorado River water to support irrigation. In addition to providing irrigation, IID also supplies electrical energy to the valley.
The Coachella Canal is a 122-mile (196 km) aqueduct that conveys Colorado River water for irrigation northwest from the All-American Canal to the Coachella Valley north of the Salton Sea in Riverside County, California.
The Sonny Bono Salton Sea National Wildlife Refuge is located in the Imperial Valley of California, 40 miles (64 km) north of the Mexican border. Situated at the southern end of the Salton Sea, the refuge protects one of the most important nesting sites and stopovers along the Pacific Flyway. Despite its location in the Colorado Desert, a subdivision of the larger Sonoran Desert, the refuge contains marine, freshwater, wetland, and agricultural habitats which provide sanctuary for hundreds of birds and wetland species, including several that have been listed as endangered or sensitive by the U.S. Fish and Wildlife Service.
The Alamo Canal was a 14 mi (23 km) long waterway that connected the Colorado River to the head of the Alamo River. The canal was constructed to provide irrigation to the Imperial Valley. A small portion of the canal was located in the United States but the majority of the canal was located in Mexico. The Alamo Canal is also known as the Imperial Canal.
The Colorado River Irrigation Company was incorporated in Colorado on January 7, 1892 for the purpose of irrigating "lands contiguous to the Colorado River." The company founders claimed to be able to irrigate 3,000,000 acres (12,000 km2), with 1,000,000 acres (4,000 km2) of that being in San Diego County, California and the remainder in Baja California, Mexico. They projected that the canal would be completed within two years. The Colorado River was described as an "inexhaustible source."
The Coachella Valley Water District is an independent special district formed in 1918. Since then, the district has grown into a multi-faceted agency that delivers irrigation and domestic (drinking) water, collects and recycles wastewater, provides regional storm water protection, replenishes the groundwater basin and promotes water conservation.
The Colorado River is a major river of the western United States and northwest Mexico in North America. Its headwaters are in the Rocky Mountains where La Poudre Pass Lake is its source. Located in north central Colorado it flows southwest through the Colorado Plateau country of western Colorado, southeastern Utah and northwestern Arizona where it flows through the Grand Canyon. It turns south near Las Vegas, Nevada, forming the Arizona–Nevada border in Lake Mead and the Arizona–California border a few miles below Davis Dam between Laughlin, Nevada and Needles, California before entering Mexico in the Colorado Desert. Most of its waters are diverted into the Imperial Valley of Southern California. In Mexico its course forms the boundary between Sonora and Baja California before entering the Gulf of California. This article describes most of the major features along the river.
Mirror Pond is an impoundment of the Deschutes River in Bend, in the U.S. state of Oregon. It is between Pacific Power's Bend Hydro dam and the Colorado dam, between RM 166 and 167. The pond is flanked by Drake, Harmon, Pageant, Brooks, Columbia, Miller's Landing, and McKay parks, as well as a number of buildings such as Pine Tavern and private homes. Some people mistakenly consider the Galveston (Tumalo) bridge the upper boundary of Mirror Pond; others call the portion of the lake between Galveston bridge and the Colorado dam "upper Mirror Pond".
The Quantification Settlement Agreement of 2003 is an agreement between the Imperial Irrigation District, the San Diego County Water Authority, and several other federal, local, and state water agencies. Under the terms of the agreement, the Imperial Irrigation District (IID) agreed to transfer large quantities of irrigation water to the San Diego County Water Authority while providing a pathway for the state of California to restore the Salton Sea. According to the IID, "The Quantification Settlement Agreement and Related Agreements are a set of inter-related contracts that settle certain disputes among the United States, the State of California, IID, Metropolitan Water District, Coachella Valley Water District and the San Diego County Water Authority."
Charles Robinson Rockwood was a United States (U.S.) civil engineer, and entrepreneur. His career was in various states of the United States, particularly in the state of California. His most significant achievement was managing the construction of a canal system that transformed the Colorado Desert (in southern California into a verdant agricultural development known as the Imperial Valley. He is also infamous for directing modifications to that same canal system which led to the accidental creation of the Salton Sea in southern California.
